Answer:
2y² + 14y - 15
Step-by-step explanation:
(2y² + 8y - 9) - (- 6y + 6)
Remove first parenthesis and distribute second by - 1
= 2y² + 8y - 9 + 6y - 6 ← collect like terms
= 2y² + 14y - 15
Answer:
The expressions are not equivalent.
Step-by-step explanation:
Three-tenths of the total volume, v =
= 0.3 × v --- (1)
But, 310x is 310 × v --- (2)
Since (1) and (2) represent the same volume,
0.3 × v = 310 × v
Divide both sides by v,
0.3 = 310 which is a contradiction.
Therefore, the expressions are not equivalent.

After 12 months andrew will have paid 516$ because there are 12 months in a year and if you multiply 516 times 12 that what you get. dough will have paid 464$ because again there are 12 months in a year and he started with 104$ so if you multiply 30$ time 12 you get 360 and if you add 104$ to that you get 464$
